[Asterisk-Users] HELP! Bad sound quality

[Rudolf Ladyzhenskii]

Hi, all

Suddenly I started to have bad sound quality. Happens with all
providers as well as with softphones connected to my * server on the
Internet.

It was OK on 1.1.17, then I migrated to 1.2.5 and it was OK for some
time. Nothing has changed in my setup, but voice quality degraged
greatly.

When I call someone, they can hear myself quite clear, but I hear lots
of interruptions in the voice. It actually gets worse. It may start as
a good clear conversation and in a few seconds it "slips" and I can
not make out what they say. Seem to only happen when calling via
Internet.
I have tried to restart both * server and my main server/gateway. I
also made sure no other traffic is going through. Nothing like P2P.
When I do use P2P I am getting my usual dowload speed, so looks like
my ISP is fine.
I run ADSL 512/128.

Any ideas on what could happen?

Thanks,
Rudolf
